Hello clublexus!

I've purchased an used 2020 lexus 300h and I'm at the 55K mile maintenance schedule. One of the to-do items is to `Clean HV battery cooling intake filter` which I assume will help cool the hybrid battery and increase MPG. Since I'm doing this DIY, I'm having difficulty in figuring out if this is required and if I should follow the recommended scheduled maintenance to do this every 5K. The instructions manual provided doesn't mention it and I can't find any instructions via Youtube, forums, etc. I'm trying my luck here to see if folks have done this maintenance before and if it is required to do this?

Thank you in advance!
